CONTAINER FOR BABY BOTTLES AND THE LIKE Filed Feb. 3, 1939 Patented May14, 1940 Isaac Lieber, New York, N. Y., assignor to Thervac Products,Inc., New York, N. Y., a corporation' of New York Application February3, 1939, Serial No. 254,414

` s claims.` (ci. 22a- 14) This invention relates to new and usefulimprovements in a container for a babys bottle or the like.

The invention proposes the construction of a container for a babysbottlelor the like characterized by a hollow cylindrical body having aclosed bottom end and upon whichY a hollow cylindrical cover is adaptedto be engaged for completely encasing a babys bottle which has beeninserted into said cylindrical body.

Specifically, it is proposed to provide the open end of said hollowcylindrical body with an annular member securely clamped thereon in amanner to receive the top edge of a corrugated sheet for holding-thesame spaced from the interior `wall of said body.

Still further it is proposed to mount insulating material in the spacebetween the adjacent faces of said corrugated sheet and the inside Wallof said body in a manner tov insulate said body to keep the contents ofthe bottle warm or cold, as desired, for a considerable length of time.

Another object of this invention is the construction cf a device asdescribed, which is simple and durable and which may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following description'and accompanying drawing, and tothe appended claims in which the variousnovel features of the invention are more particularly set forth,

In the accompanying drawing forming a material part of` this disclosure-Fig. 1 is a perspective view of a container for a babys bottle or thelike constructed according to this invention.

Fig. 2 is a vertical sectional View on the line 2 2 of Fig. 1.

Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 2.

Fig. 4 is a perspective view of the heat insulating material andcorrugated sheet per se.

The container for a babys bottle or the like, according to thisinvention, comprises a hollow cylindrical body I having a closed bottomend and an open top end for permitting a babys bot tle or the like to beinserted. The hollow cylindrical body has a double wall consisting of aninner wallsection Illa, and an outer wall section Illb. The wallsections are constructed of cardboard or-similar material, preferably`pasted together, and the top edge of the inner wall section Illa extendsbeyond the top edge of the outer wall section 10b. A bottom wall II isprovided for closing the bottom end of the hollow cylindrical body Ill.This bottom wall I I is of a diameter equal to the outside diameter ofthe inner wall section Illa and is rested there-against as shown in Fig.2. The bottom edge i017 of the outer wall section Itb is turned underand en,- gages the bottom face of the bottom wall Il for rigidlymaintaining the same in position against the bottom end oithe inner wallsection Illa. The bottom wall Il may be secured in any other manner.

A hollow cylindrical cover I2 engages over the top end of the hollowcylindrical body Ill for completely encasing the bottle inserted into,the body I0. The hollow cylindrical cover I2 is formed of cardboard orsimilar material and is of a diameter substantially equal to thediameter of the outer wall section lilb of the hollow cylindrical bodyI0. In engaging the hollow cylindrical `cover I2 upon the body I0 thesame engages around the periphery of the inner wall section Ia and ispassed thereover in end alignment with the outer wall section I0b asshown in Fig. 3.

A means is provided for closing the top end of the hollow cylindricalcover I2. This means comprises a top wall i3 having an outer diameterequal to the inside diameter of` the hollow cylindrical cover I2. Thetop edge I2a of the hollow cylindrical cover I2 is bent inwards andengages the top face of the topwall I3 for holding the same in positionwithin the cylindrical cover I2.

The top wall I3 may be secured in any other way.

An annular member Il, of metal or other similar material, is mounted onthe top end of the inner wall section Ida of the hollow cylindrical bodyl0 and forms an inwardly extending flange.

The outer edge portion of the annular member It is formed with a groovelia (see Fig. 2), the material oi which is tightly clamped upon the edgeof the inner wall section lila.. The top edge portion of the inner wallsection Ia is slightly compressed for permitting the outer edge portionof the groove Ilia to remain substantially flush with the outside faceof the wall of the section Illa so that the cover I2 may be engagedthereon.

A corrugated disc I5 is rested upon the inner face of the bottom wall IIforming a plurality of. air spaces I6 between the adjacent faces of thedisc I5 and the bottom wall II for insulating the inside of the hollowcylindrical body I0 from the outside thereof. A corrugated sheet I'I isengaged within the hollow cylindricalv body' IllV and has its facespaced from the adjacent face of the inside of the hollow cylindricalbody I0. The

bottom end of the corrugated sheet I'I rests upon the top face of thecorrugated disc I5. The inner edge portion of the annular member I4 isformed with a ange -Idb behind which the top edge of the corrugatedsheet Il extends in a manner to hold the corrugated sheet axially of thecylindrical body I0 to maintain the space between the adjacent faces ofthe sheet Il and the cylindrical body I0.

In constructing the container the insulating material I8 is securelyattached to one face of the corrugated sheet Il and is adapted to beplaced into the container at the same time the sheet is engaged therein.The insulating material is secured thereto for maintaining the sameextended along the entire length thereof and for preventing it fromsliding downwards withf in the space between the adjacent faces ol thesheet I1 and the body I0.

The operation of the device is as follows:

'I'he milk or other substance to be placed within the bottle is puttherein and the entire bottle is heated, or cooled, and then placedwithin the container through the open end of the hollow cylindrical bodyI0. The hollow cylindrical cover I2 is engaged thereon for completelysealing the interior of the container from the outside atmosphere forkeeping the contents of the bottle warm or cold until such time as it isneeded.

While I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts without departing from the spirit orthe scope of the appended claims.

Having thus described my invention, what I claim as new and desire 'tosecure by United States Letters Patent is:

1. In a container for baby bottles and the like, a hollow cylindricalbody having a closed bot tom end, a corrugated disc rested on saidclosed bottom end, an annular member mounted on the top end of said bodyand extending radial inwards and at its inner edge having alongitudinally inwardly extending flange portion, and a tubular heatinsulation unit comprising flexble heat insulation material adjacent andextending around the side wall of said body and at itsrtop stoppingshort of said flange anda ilexible sheet extending along said heatinsulation material and at its bottom edge resting on said disc and atits top edge projecting above said heat insulation material and behindsaid flange portion and having free side edges adjacent each other,whereby one of said side. edgesmay be gripped and pulled for easilyremovingv stopping short of said ilange and a flexible sheet extendingalong said heat insulation material and at its bottom edge resting onsaid disc and at' its top edge projecting above said heat insulationmaterial and behind said flange portion and having free side edgesadjacent each other, whereby one of said side edges may be gripped andpulled for easily removing said heat insulation unit, said heatinsulation material and flexible sheet being pasted together as a unit.
